iPhone battery life

[ki8aras]

About a month ago I managed to gather 1000 euros to buy a new smartphone, I had a galaxy s8+ and my main objective was to get a flagship that also had better battery life

 

after some digging I saw that reviewers were praising the battery life of the 11 pro max and I said, sure why not(this would be my first time using iOS)

 

When I got it I expected about 8 hours of sot with my usage(my s8+ had about 6) 

 

 

but you better believe I am astonished because right now I am sitting at 7 hours 32 minutes of sot with 43% remaining???what kind of sorcery is this??

Part of it is the sorcery of “brand new lithium battery” I suspect.  Every time you recharge a lithium battery it gets a bit lower capacity.  There’s also the lower refresh rate of the screen and running a more polished OS and some other stuff.

Reason for this is that people keep on spreading nonsense and only looking at battery rated capacity. 3000mAh on Android is one thing, 3000mAh with iOS and thus iPhone is entirely different one. Same reason why iPhones only have 4GB of RAM and somehow run faster or at least about the same as Androids with absurd 12GB of RAM.

 

Reason for this is the fact that iOS is highly optimized for iPhones. OS is specifically crafted for hardware used in iPhones. Where Android is like Windows or Linux. A general purpose OS meant to run on bunch of ARM based chipsets, each running own drivers in bunch of combinations. Sort of like comparing consoles and PC's when it comes to gaming. Consoles are that efficient because everything is optimized for that model of console and that's it. Where PC has 5000 motherboards, 10.000 CPU's, 50.000 graphic cards and all come in millions of combinations. Having ability to support so many different things usually comes with a performance tax and that's clearly evident. I guess one could optimize it on same level as iOS and totally rewrite it, but no one seems to be bothered doing that.

 

Which is why I always say people need to frigging stop making conclusions on battery life just by looking at capacity of batteries in iPhones, because that number is entirely irrelevant and meaningless. Looking at battery capacity and comparing it to other iPhones, yes, you can make some sense of it, but comparing it to Android phones it's pointless.

Depends on your usage. Just browsing on chrome or any social media won't drain that much battery.

I mean yeah I knew about apple’s polish and optimization but I didn’t expect it to make THAT MUCH of a difference

Little bits add up.  I agree mah is an inexact way to measure phone life because different phones have different hardware.  This is why reviews are good.  One can’t trust manufacturers  to accurately report the ability of their products in anything but the loosest way.  There’s too much marketing and no regulation anymore.  The people that design the phones know the truth though.  A more efficient phone will have a smaller battery.

Brand new phone with 3968mAh battery vs worn 3500mAh that uses an older process node?

 

Was your S8+ an Exynos model?

It doesn't. I had Xiaomi with 3000mAh battery. And now I have iPhone XR with 2941mAh battery and Xiaomi never ever had such high autonomy as iPhone, not even when new. Granted chipset in iPhone is a bit newer, but still. Most of optimization comes from OS and Android just never will be this efficient. Unless vendors will really try hard and rewrite it to be absurdly optimized for their hardware. Which no one will do because they all shit like 15 new phones every week and they can't afford spending so much time working on software. Where Apple can and does for those 4 phones and few tablets they release every year.

I didn't say ios isn't optimized. Exynos is known for having battery issues, especially older ones. Also it has a slightly higher res screen, slightly lower battery capacity and most importantly it runs a heavily skinned version of Android.

Just let the delusional sheep be in their echo chamber... 

 

Here is a comparison of same process node flagship with basically same battery capacity

I mistrust stuff that uses the term “delusional”  and “echo chamber” on principal.  Doesn’t mean you’re wrong though.  Testing is important.  It can be messed with by marketing elements too though.   Makes it indicative but not definitive.

 

to add another data point,  I did see another test in a video that was comparing the iphoneSE, 11, 11 pro, and several flagship android phones.  The 11 pro did not win though it did come in second.  (The iphoneSE was dead last by a lot, with its MUCH smaller battery which was the point of the video). I don’t know how big the batteries were in the compared phones.  Runtime was what was being measured.  Adding a larger battery increases runtime.  
 

now we just need bunch more that agree and we might have something.

The iPhone 11 Pro Max also has a larger, significantly higher-resolution screen and a CPU that runs rings around the Snapdragon 855.  You might want to ask why Redmi barely edges ahead in a test where its weaker hardware should confer an advantage.

And a third.  Missing in this one is refresh rate.  Apple is supposed to have a lower (and totally fine) refresh rate making it use less juice separate from OS savings which are the focus here it seems.  The issue is there are many parts.  So also a partial data point making three partial data points.  
 

Why do I get the feeling marketers have pooped in the water and stirred vigorously for their own gain?

I thought the K20 Pro refreshed at 60Hz?  Like LV said, Apple polls responses at 120Hz.

Apple does Poll the screen at 120Hz though not 60Hz.

Poll for touch or actually doing screen draws?

Might.  No idea.  It was mentioned as an issue in the video I watched.  I really want to link it.  Was hardware unboxed maybe?  Days old. “Refresh rate” can be described several ways on phones it seems.

It's what a cursory search indicated, at any rate.  You might not be looking at the K20 Pro, since that was released in the middle of last year when anything higher than 60Hz was still a big deal.

 

Let's put it this way: screen refresh rate is different than the polling rate, and the former has much more of a hit on battery life than the latter.

Poll für touch. Screen refresh rate is classic 60 Hz
